But with a fleck of DIY cognition, you can repair scratches, kerb harm, bends, and corrosion at a fraction of the price that many machine dealers charge!

1. 1

   Make clean the expanse surrounding the damage with paint thinner. Buy a non-acidic cleaner and use it to a clean microfiber cloth or soft-bristled detailing brush. Scrub the damaged areas of the wheels with your fabric or brush by moving it in small-scale circles. For areas with lots of buildup, be generous with the cleaner and be certain they get a thorough scrub. ^[ane]

   • Focus your efforts on the most damaged areas.

   Wipe some spot putty onto the scratched region. Squeeze a coin-sized dab of putty onto a 2 inch (five.1 cm) putty pocketknife. Drag the knife at a 45-degree angle over the scratched expanse and press it down until it's every bit level with the alloy wheel as possible. The spot putty will offset to set up within a few minutes, so work every bit fast as possible.^[3]

   • E'er piece of work in a cool, well-ventilated area.
   • Avoid cold, clammy areas—the putty will not dry properly.
   • Purchase spot putty from a section store or in blend cycle repair kits available from online suppliers.

1. 1

   Apply lube around the circumference of the rim. Before you lot pry off your rim, lubricate its outside edge where it meets the bicycle. If your lubricant is in a spray tin can, hold it well-nigh i inch (2.5 cm) over the circumference and apply it.

   Oestrus the aptitude surface area to 302 °F (150 °C) from the inside with a blow torch. Agree the digital thermometer nigh 1 foot (0.thirty thou) from the outside edge of the alloy. From the inside, apply the blow torch at a 45-degree angle, moving side to side over the bend. Continue this motility until the blend wheel reads 302 °F (150 °C) on the thermometer.^[8]

   • Keep the blow torch about 1 inch (two.5 cm) from the wheel.

5. five

   Detect a piece of forest that fits into your paring. Your all-time bet is a curved sanding block from an office supply store or online supplier. Select a piece of wood with a curve every bit close as possible to the dent, but don't stress if it doesn't fit perfectly.^[nine]

Continue this until you notice the pitting—the pocket-sized holes created by localized corrosion—kickoff to fade.^[14]

Proceed sanding side to side until you don't notice a change in the visibility of the pitting. Switch to 400-grit sandpaper and continue sanding until the pitting is barely visible or not visible at all.^[xv]

   • Don't worry about applying equally much pressure when using finer sandpaper.

6. vi

   Utilize wheel wax to foreclose farther oxidation. Dip your foam applicator into wheel wax and rub information technology direct onto your blend wheels. Be certain to apply a generous corporeality and spread information technology evenly over the unabridged blend surface. Afterward, remove it with a soft cotton towel.^[16]

   • E'er use clean cotton fiber towels to avert contaminating your alloy wheel with clay.
